CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority under 35 U.S.C. §119 of
U.S. Provisional Application Ser. No. 61/407,195, filed on Oct. 27, 2010,
and U.S. Provisional Application Ser. No. 61/426,212 filed on Dec. 22,
2010 the contents of which are relied upon and incorporated herein by

BACKGROUND

[0002] 1. Field of the Disclosure

[0003] The disclosure relates generally to fiber optic module assemblies
and more particularly to fiber optic module assemblies having flexible
cables extending outside of the module assembly which may be used in
limited space applications.

[0004] 2. Technical Field

[0005] In the field of fiber optics, installation space and operator
access are not unlimited. In some applications, for example,
retro-fitting an existing fiber optic system or placing fiber optic
systems into unusual locations, it is not always convenient for operators
to install, test, troubleshoot or otherwise maintain optical systems. For
example, in Fiber to the Antenna (FTTA) applications, fiber optic systems
are typically placed into small cabinets, boxes or canisters that are not
always properly sealed. Exposure to environmental stresses, e.g.,
temperature extremes, humidity and particulate intrusion, to name a few,
can adversely affect optical performance or even damage components.
Driven by high capacity demands, such systems rely upon multi-fiber
cables and multi-fiber connectors that are sensitive to environmental
stresses. Space constraints make replacing compromised components
difficult. What is needed is a fiber optic module that has installation
flexibility as well as integral sealing of sensitive components to
mitigate any environmental and physical constraints.

[0006] No admission is made that any reference cited herein constitutes
prior art. Applicant expressly reserves the right to challenge the
accuracy and pertinency of any cited documents.

SUMMARY

[0007] One aspect of the disclosure relates to a fiber optic module. The

sub-assembly including at least one fiber optic cable passing through,
for example, the at least one input aperture, at least one multi-fiber
connector on an end of the fiber optic cable, and at least one single
fiber connector on an opposite end of the fiber optic cable. The
multi-fiber connector may be in optical communication with the at least
one single fiber connector, the multi-fiber connector capable of flexing
on the at least one fiber optic cable relative to the module housing.

[0008] An additional aspect of the disclosure relates to a module
sub-assembly, including at least one fiber optic cable, at least one
multi-fiber connector on an end of the fiber optic cable, and at least
one single fiber connector on an opposite end of the fiber optic cable.
The multi-fiber connector may be in optical communication with the at
least one single fiber connector. The sub-assembly may further include a
demarcation and a furcation, the demarcation being located along the at
least one fiber optic cable between the multi-fiber connector and the
furcation, the furcation being located along the at least one fiber optic
cable between the demarcation and the at least one single fiber
connector. Furthermore, the sub-assembly may include a compression
fitting, the compression fitting being about the at least one fiber optic
cable between the demarcation and the multi-fiber connector.

[0009] An additional aspect of the disclosure relates to embodiments of a
surface mountable module assembly, including brackets for holding the
fiber optic module, for example, flush to a mounting surface, at an angle
to a mounting surface, and orthogonal to a mounting surface.

DETAILED DESCRIPTION

[0029] Reference is now made in detail to exemplary embodiments of the
disclosure, examples of which are illustrated in the accompanying
drawings. Whenever possible, identical or similar reference numerals are
used throughout the drawings to refer to identical or similar parts.

[0030] The disclosure herein is to a fiber optic module assembly having at
least one module sub-assembly and a module housing for receiving the
module sub-assembly. The module sub-assembly defines a fiber optic
harness that may be disposed partially inside the module housing and
partially outside the module housing, the external portion being flexible
relative to the module housing. In exemplary embodiments, a hardened
multi-fiber connector, suitable for extreme environmental exposure, may
be on an end of the module sub-assembly that is partially outside of the
module housing. The module sub-assembly may include a sealed portion and
an unsealed portion, the sealed portion being partially disposed outside
of the module housing. The flexibility of the external portion of the
module sub-assembly enables ease of access, for example, when connecting
another cable to the module assembly, by allowing freedom of movement of
the external portion of the module sub-assembly. Furthermore, the
disclosure relates to apparatuses for mounting the module assembly, for
example, to a mounting surface, a wall, a cabinet and a rack.

[0031] A fiber optic module 10 (FIG. 1) may include a module housing 20
and a partially sealed module sub-assembly 30. Sub-assembly 30 may be at
least partially located within module housing 20. A portion of
sub-assembly 30 may, in exemplary embodiments, be located partially
outside of module housing 20 by a distance 12. Distance 12 may be defined
as an exterior distance from module housing 20 to an end of sub-assembly
30. In exemplary embodiments, distance 12 may be adjustable, for example,
from a first distance of 5-10 centimeters (cm) to a second distance of
15-20 centimeters.

[0032] Module housing 20 (FIGS. 1 and 2) may include a bottom 21 and at
least two walls, e.g., a first wall 22 and a second wall 24. In exemplary
embodiments, first wall 22 and second wall 24 may extend from bottom 21.
Module housing 20, in exemplary embodiments, defines at least one
connector adapter aperture 23, for example, positioned on first wall 22,
and in further exemplary embodiments defines at least one input aperture
25, for example, positioned on second wall 24. Adapter aperture 23 and
input aperture 25 may provide access to an interior space 28. In
exemplary embodiments, the at least two walls may be substantially
aligned to each other, for example, may be substantially parallel. In
other exemplary embodiments the at least two walls may be substantially
at angles relative to each other, for example, not substantially
parallel, and in yet other exemplary embodiments the at least two walls
may be about 60 degrees relative to each other.

[0033] Module housing 20 may further include at least one attachment
feature, and in exemplary embodiments, a plurality of attachment features
26a, 26b located within interior space 28, for securing module
sub-assembly 30 within module housing 20. For example, module
sub-assembly 30 may be secured in part by attachment feature 26a and in
part by attachment feature 26b. Attachment features 26a, 26b may be
selected from attachment features being selected from the group
consisting of a hook, a tab, an aperture, a push-out feature, and
combinations of the same. In exemplary embodiments, attachment features
26a, 26b are sheet metal push-out features and may cooperate with, for
example, a secondary securing means, for example, a strap or a tie, for
securing module sub-assembly 30.

[0034] Module sub-assembly 30 (FIGS. 1 and 3), may include a sealed
portion 30a and an unsealed portion 30b. Sealed portion 30a may include
at least one fiber optic cable 32 having at least one optical fiber
disposed inside, at least one multi-fiber connector 31 on one end of
sub-assembly 30 in communication with the at least one optical fiber.
More specifically, multi-fiber connector 31 may be a hardened multi-fiber
connector disposed on an end of cable 32. Cable 32 may be, for example, a
rugged drop cable such as SST Flat Indoor/Outdoor Drop Cable available
from Corning Cable Systems, Hickory NC. A demarcation 33 may be disposed,
for example, on the other end of cable 32, providing a sealed portion
30a. Demarcation 33 may be, for example, a tube for receiving cable 32 at
an end of the tube, with the at least one optical fiber passing through
the tube. A curable sealant, for example, epoxy or RTV, may be disposed
inside the tube, surrounding the end of cable 32 and the at least one
optical fiber, locking cable 32 and the at least one optical fiber inside
the tube. Sealed portion 30a may be sealed, for example, from
environmental influences, including, but not limited to, dust and water
intrusion. Multi-fiber connector 31, being a hardened connector, for
example, an OptiTip® Connector available from Corning Cable Systems
(though other hardened connectors are possible), is sealed in an
unconnected state by a threaded dust cap, and in a connected state by
connection to another hardened connector 19 (see FIG. 14), or a hardened
adapter, sealing sealed portion 30a.

[0035] Unsealed portion 30b may include, in exemplary embodiments, a
furcation 35 disposed on an end of an unsealed cable 34, for example, the
at least one optical fiber exiting the other end of demarcation 33. In
exemplary embodiments, unsealed cable 34 exits demarcation 33 and enters
furcation 35. Unsealed cable 34, in some embodiments, may be at least one
multi-fiber ribbon, for example, at least one 12 fiber ribbon, encased,
for example, by a braided sleeve. In exemplary embodiments, furcation 35
may transition the at least one multi-fiber ribbon from a ribbon into at
least one single optical fiber 36. Upon exiting furcation 35, a plurality
of single optical fibers 36 may be grouped into at least one bundle 36a
by the application of, for example, a wrap 37, for routing. Each of
single optical fibers 36 may be terminated by a single fiber connector
38, for example, such as DC,SC, SC-APC, and LC connectors to name a few.
In exemplary embodiments, the 12 fiber ribbon is furcated by furcation 35
into 12 single optical fibers 36, which are terminated by 12 SC-APC
connectors. It should be understood that in exemplary embodiments each of
single fiber connectors 38 is in optical communication with multi-fiber
connector 31 by way of a single optical fiber that terminates at both
multi-fiber connector 31 and single fiber connector 38.

[0036] In exemplary embodiments, a compression fitting 40 may be disposed
on cable 32 between connector 31 and furcation 33, including a treaded
nut 42, a grommet 44 and a threaded body 46, grommet 44 being between
threaded nut 42 and threaded body 46. Compression fitting 40 may engage,
for example, input aperture 25 for securing module sub-assembly 30 to
housing 20. Grommet 44 may include an opening having an inner profile
that closely matches the outer profile of cable 32. Grommet 44 may be
made from, for example, an elastomer that when compressed by tightening
threaded nut 42 to threaded body 46 grips cable 32 with a compressive
force and holds sub-assembly 30. Compression fitting 40 enables
adjustments to distance 12 by loosening threaded nut 42, releasing the
compressive force, allowing cable 32 to slide temporarily within grommet
44 for making distance 12 greater or smaller, then retightening threaded
nut 42 to lock cable 32 at desired distance 12.

[0037] In exemplary embodiments, module sub-assembly 30 may be routed
interior space 28 by coiling module sub-assembly 30. Cable 32, being
secured to housing 20 at input aperture 25 by, for example, compression
fitting 40, may be coiled at least once, placing demarcation 33 alongside
attachment features 26b. In exemplary embodiments, cable 32 may be
proximate to bottom 21, and may rest against alignment pins 27b to
prevent any unwanted cable movement. A fastener 13, for example, a cable
tie, zip-tie or tie-wrap, may engage each of attachment features 26b,
wrapping around demarcation 33, thus holding demarcation 33 alongside
alignment features 26b. Unsealed cable 34 may be further coiled at least
once, for example, above cable 32, placing furcation 35 along or between
attachment features 26a. Another fastener 13 may engage attachment
features 26a, wrapping around furcation 35. In some exemplary
embodiments, furcation 35 may be nestled substantially between other
alignment pins 27a, for example, to prevent furcation 35 from twisting
under torque generated by the shape memory of cable 32 and unsealed cable
34. Single optical fibers 36, and corresponding bundles 36a may be routed
from furcation 35 to place single fiber connectors 38 proximal to adapter
apertures 23. Single fiber connectors 38 each may be inserted into one of
a plurality of adapters 39 disposed at adapter apertures 23. In exemplary
embodiments, adapters 39 are duplex adapters configured to receive two
each of connectors 38.

[0038] In alternate embodiments, a first alternate fiber optic module 10'
(FIG. 4) may include alternate module housing 50 having a cover 59
attached to housing 50 by a hinge 59a. Module sub-assembly 30 may be
secured to housing 50 through a first alternate input aperture 55. A
plurality of alternate adapter apertures 53 may receive adapters 39.
Connectors 38 may be inserted into adapters 39.

[0039] In yet another alternate embodiment, a second alternate fiber optic
module 10'' (FIG. 5) may include alternate module housing 60 having a
cover 69 attached to housing 60 by a hinge 69a. A pair of module
sub-assemblies 30 may be secured to housing 60 through a pair of
alternate input apertures 65. A plurality of alternate adapter apertures
63 may receive adapters 39. Connectors 38 may be inserted into adapters
39.

[0040] In exemplary embodiments, multi-fiber connector 31 may be capable
of flexing on, for example, cable 32, relative to module housing 20
(FIGS. 6-8). Having distance 12 between connector 31 and housing 20
exposes a length of cable 32, enabling flexing. In representative
embodiments, connector 31 may flex up to 180 degrees relative to housing
20, easing routing of, for example, trunk cables in situations where
space and access are limited. Flexing may be limited only by physical
constraints of the kind of cable used in sub-assembly 30; for example, if
cable 32 is a bend preferential cable such as a flat drop cable, bending
may be substantially free in X and Y axes. Z axis flexing may be realized
by applying torsion to connector 31, the torsion being transmitted to
cable 32, twisting cable 32 up to 90 degrees. If cable 32, for example,
is a non-preferential bend cable, flexing may be substantially limited
only by environmental constraints; for example, limited spatial freedom
to flex. In exemplary embodiments, connector 31 may flex toward first
wall 22 up to 120 degrees (FIG. 6), effectively pointing connector 31
toward front wall 22, enabling connection to, for example, another fiber
optic connector on a trunk cable that may be routed from the front of
module 10. In another exemplary embodiment, connector 31 may flex away
from first wall 22 up to 60 degrees (FIG. 7), effectively pointing
connector 31 away from front wall 22, enabling connection to, for
example, yet another fiber optic connector on another trunk cable that
may be routed from the rear of module 10. Of course, cables being routed
from any intervening direction may be connected to connector 31. In yet
another exemplary embodiment, sub-assembly 30 may twist (FIG. 8) by the
application of a torque to connector 31, enabling flexibility in the Z
axis to accommodate, for example, connection to yet another fiber optic
connector on yet another trunk cable being routed, for example, from
above or below module 10.

[0041] Flexibility of sub-assembly 30 relative to, for example, housing
20, may expand installation opportunities for module 10. Module 10 may be
installed in any one of a plurality of wall mountable module assemblies.
In an exemplary wall mountable module assembly, a side insertion mounting
bracket 70 (FIG. 9), in an exemplary embodiment, may include at least one
first leg 72 defining a module mounting area having at least one module
mounting aperture 73 for engaging push-lock pins 11 (FIG. 10). Mounting
bracket 70 may have at least one second leg 74 defining a surface, or
wall, mounting area that may have at least one mounting surface aperture
75. First leg 72 and second leg 74, in exemplary embodiments, may be
orthogonal to each other for mounting at least one module 10 to a
mounting surface, for example, a wall, with at least one module 10
engaging mounting bracket 70 substantially in alignment with the mounting
surface. Put another way, mounting bracket 70 enables at least one module
10 to be mounted substantially flush to a wall or other mounting surface
(see FIG. 19). In exemplary embodiments, a plurality of modules 10 may be
mounted together in mounting bracket 70 in substantially the same
alignment without occupying large amounts of, for example, wall area or
cabinet volume. Side mounting bracket 70 may be made from a plastic or a
metal, and in exemplary embodiments may be a stamped sheet metal bracket.

[0042] In another exemplary wall mountable module assembly embodiment, an
angular insertion mounting bracket 80 (FIG. 11) may mount, in exemplary
embodiments, at least one module 10 at an angle to a mounting surface.
Module 10 may engage mounting bracket 80 at an angle, for example,
greater than zero degrees but less than 90 degrees, relative to the
mounting surface, for example, a wall. In exemplary embodiments, module
10 may engage mounting bracket 80 at a 15 degree angle relative to the
mounting surface. Angular mounting bracket 80 may include at least one
first leg 82 defining another module mounting area having at least one
module mounting aperture 83 for engaging push-lock pins 11 (FIG. 12).
Mounting bracket 80 may have at least one second leg 84 defining another
surface, or wall, mounting area that may have at least one mounting
surface aperture 85. First leg 82 and second leg 84, in exemplary
embodiments, may be non-orthogonal to each other for mounting at least
one module 10 to a mounting surface, for example, a wall, with at least
one module 10 engaging mounting bracket 80 substantially an angle less
than 90 degrees, for example, 75 degrees, relative the mounting surface.
Put another way, mounting bracket 80 enables at least one module 10 to be
inserted at an angle less than 90 degrees to a wall or other mounting
surface (see FIGS. 12 and 19). In exemplary embodiments, a plurality of
modules 10 may be mounted together in mounting bracket 80 in
substantially the same alignment without occupying large amounts of, for
example, wall area or cabinet volume. Angled mounting bracket 80 may be
made from a plastic or a metal, and in exemplary embodiments may be a
stamped sheet metal bracket.

[0043] At least one vertical support 86 may be in communication with at
least one horizontal support 88. Horizontal support 88 may include at
least one routing guide aperture 89 for receiving, for example, a routing
guide 14 or clip for routing jumper cables (not shown) that may connect
to adapters 39. Vertical support 86, in exemplary embodiments, may be at
about a 15 degree angle to second leg 84 and orthogonal to first leg 82.

[0044] In yet another wall mountable module assembly embodiment, an
orthogonal insertion mounting bracket 90 (FIG. 13) may mount, in
exemplary embodiments, at least one module 10 orthogonal to a mounting
surface, for example, a wall in a data closet or cabinet. Module 10 may
engage mounting bracket 90 orthogonal to the mounting surface, for
example, a wall. Angular mounting bracket 90 may include at least one
first leg 92 defining yet another module mounting area having at least
one module mounting aperture 93 for engaging push-lock pins 11 (FIG. 14).
Mounting bracket 90 may have at least one second leg 94 defining yet
another surface, or wall, mounting area that may have at least one
mounting surface aperture 95. First leg 92 and second leg 94, in
exemplary embodiments, may be substantially aligned to each other for
mounting at least one module 10 to a mounting surface, for example, a
wall, with at least one module 10 engaging mounting bracket 90
substantially an angle of about 90 degrees relative the mounting surface.
Put another way, mounting bracket 90 enables at least one module 10 to be
inserted straight in to a wall or other mounting surface (see FIGS. 14
and 19). In exemplary embodiments, a plurality of modules 10 may be
mounted together in mounting bracket 80 in substantially the same
alignment without occupying large amounts of, for example, wall area or
cabinet volume. Orthogonal mounting bracket 90 may be made from a plastic
or a metal, and in exemplary embodiments may be a stamped sheet metal
bracket.

[0045] At least one vertical support 96 may cooperate with two front legs
92 to define an insertion aperture 97. Further, vertical support 96 may
be in communication with at least one tab 98. Tab 98 may include at least
one routing guide aperture 99 for receiving, for example, a routing guide
14 or similar clip for routing jumper cables (not shown) that may connect
to adapters 39. Vertical support 96, in exemplary embodiments, may be
orthogonal to second leg 94 and first leg 92.

[0046] By way of example, an exemplary trunk cable 18 having a trunk
connector 19, for example, capable of mating with connector 31, may be
routed from substantially above the wall mounted module assembly located
in orthogonal insertion mounting bracket 90 (FIG. 14). Connector 31 may
flex on cable 32 to accommodate the overhead routing, effectively laying
alongside the mounting surface (not shown).

[0047] In further embodiments, at least one sub-assembly 30 may be located
in one of shelf module assemblies 100, 200 (FIGS. 15 and 16). In
exemplary embodiments, shelf module assemblies 100, 200 may include a
shelf module housing 120, 220 and at least one partially sealed module
sub-assembly 30. A portion of sub-assembly 30 may, in exemplary
embodiments, be located partially outside of module housing 120, 220 by a
distance 12. Distance 12 may be defined as an exterior distance from
module housing 120, 220 to an end of sub-assembly 30. Shelf module
assemblies 100, 200 may be configured, for example, having at least one
flange 102, 202, for securing to a rack, for example, located in a data
center. Module housing 120, 220 may have a bottom 121, 131 and at least
two walls, e.g., a first shelf wall 122, 222 and a second shelf wall 124,
224. In exemplary embodiments, first shelf wall 122, 222 and second shelf
wall 124, 224 may extend from bottom 121, 221. Module housing 120, 220,
in exemplary embodiments, defines at least one shelf adapter aperture
123, 223, for example, positioned on first shelf wall 122, 222 and in
further exemplary embodiments defines a plurality of shelf adapter
apertures 123, 223. Module housing 120 may define at least one shelf
input aperture 125, for example, positioned on second shelf wall 124.
Module housing 220 may define at least two shelf input apertures 225, for
example, positioned on second shelf wall 224. Adapter aperture 123, 223
and input aperture 125, 225 may provide access to an interior space 128,
228. In exemplary embodiments, walls 122, 222 and 124, 224, respectively,
may be substantially aligned to each other, for example, may be
substantially parallel. In other exemplary embodiments, walls 122, 222
and 124, 224, respectively, may be substantially at angles relative to
each other, for example, not parallel. As depicted, shelf module
assemblies 100, 200 may be, for example, 1 U rack mountable assemblies,
but larger assemblies, for example, 2 U, 3 U or larger may be
contemplated within the scope of this disclosure.

[0048] In other embodiments, an alternate shelf module assembly 300 (FIGS.
17 and 18) may include at least one module 10, and in exemplary
embodiments, may contain a pair of modules 10. Shelf module assembly 300
may include a rack mountable 1 U shelf 320 for receiving at least one
module 10. Rack mountable shelf 320 may be configured to attach to, for
example a standard rack 302. In exemplary embodiments, modules 10 may be
mounted, for example, horizontally, enabling operator access to each
sub-assembly 30, for example, for routing feeder or trunk cables from
rack 302 to each sub-assembly 30. It may be appreciated that more than
one level of modules 10 may be arranged in yet other alternate shelf
module assemblies (not shown) and such embodiments are within the scope
of this disclosure.

[0049] In exemplary embodiments, one or more modules 10, contained in any
one or more of brackets 50, 60 or 70, may be located in a cabinet, for
example, a base cabinet assembly 400 (FIG. 19). A base cabinet 420 may be
in communication with, for example, a Remote Radio Head 434 mounted, for
example, on an antenna 430, or on a similarly tall structure, for
example, a building.

modifications and variations can be made without departing from the
spirit or scope of the invention. Since modifications combinations,
sub-combinations and variations of the disclosed embodiments
incorporating the spirit and substance of the invention may occur to
